Kitchen sink plug hole/waste pipe leak

[Teleri]

Hi there

Could someone help identify the waste pipe (think that's what it is) coming from the bottom of the basin/plug hole, feeding into the other pipes?

It has a leak where it connects to the bottom of the basin, so I'm thinking about replacing it if it's a standard part.

If so can you tell me what measurement I should take to find correct fittings?



Thanks

It looks like a basket strainer waste and might just need tightening up.
